Description

Technical Field

[0001] This utility model relates to the field of clamping tooling technology, specifically to a clamping tooling for bicycle frame processing. Background Technology

[0002] Bicycle frame machining fixtures are specialized clamping systems used in various frame manufacturing processes (such as welding, drilling, and milling) to precisely position and securely fix frame tubing, joints, or semi-finished / finished products. Their core function is to ensure that the frame maintains the precise geometric position and angles required by the design during machining (such as the head tube, bottom bracket, and rear fork), and effectively resists displacement or vibration caused by machining forces (cutting forces, welding heat deformation, etc.).

[0003] Chinese utility model patent CN211540076U discloses a clamping device for processing bicycle frames, including "a workbench support, a workbench, a fixing plate, mounting bolt holes, a mounting plate, an adjustable clamping plate structure, a slide rail, an electric hydraulic cylinder switch, and a protective pad; the fixing plate is welded to the right side of the upper part of the workbench; the mounting plate is welded to the lower part of the workbench support; the adjustable clamping plate structure is installed on the upper left side of the workbench; and the slide rail is screwed to the left side of the upper part of the workbench." However, this clamping device directly places the frame on the workbench and pushes it, which causes friction between the frame and the workbench during the pushing process, damaging the frame. Furthermore, after clamping the frame, the device can only process one side of the frame, while the side in contact with the workbench is difficult to operate, requiring the frame to be flipped, which is time-consuming and laborious. Utility Model Content

[0004] The purpose of this invention is to provide a clamping fixture for bicycle frame processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping fixture for bicycle frame processing, comprising a device frame, a drive assembly on the upper part of the device frame, and a clamping assembly on one side of the drive assembly; the device frame includes an operating table, with a bearing rotatably mounted on the upper end of the operating table; the drive assembly includes a second servo motor, with a second threaded rod rotatably mounted on the front end of the second servo motor, and a fixed connecting plate on the front end of the second threaded rod, the fixed connecting plate having a bearing rotatably connected to one side of the second threaded rod; the clamping assembly includes a sliding cylinder block, which is slidably mounted on the outer surface of the second threaded rod, and a connecting block is fixedly mounted on the outer surface of the sliding cylinder block; arc-shaped movable parts are rotatably mounted on both sides of the connecting block, and the connecting block and the arc-shaped movable parts are connected by a connecting limit rod, with limit rings on both sides of the connecting limit rod; a second fixing rod is fixedly mounted inside each arc-shaped movable part, and a clamping block is fixedly mounted on the front end of each arc-shaped movable part; a protective rubber pad is bolted to one side of the clamping block.

[0006] The beneficial effects of this utility model are as follows: by starting the second servo motor, the second threaded rotating rod is driven to rotate, which in turn drives the sliding cylinder block and the connecting block to slide. When the connecting block slides forward, it will drive the arc-shaped movable parts on both sides to push forward. At the same time, the arc-shaped movable parts are guided by the rotating block, and the arc-shaped movable parts on both sides will clamp towards the center. Finally, it will drive the clamping blocks and protective rubber pads on both sides to clamp towards the center. This can achieve the effect of quickly clamping the bicycle frame when the device is in use, which is convenient for subsequent processing, avoids damage to the frame, and improves the practicality of the device.

[0007] To achieve the desired clamping height for transporting the vehicle frame to the clamping assembly: The following configuration is further provided: a first servo motor is provided inside the operating table, the first servo motor is fixed to the bottom plate of the operating table by bolts, a first threaded rotating rod is rotatably installed at the upper end of the first servo motor, a threaded sleeve is slidably installed at the upper end of the first threaded rotating rod, and a lifting plate is fixedly installed at the upper end of the threaded sleeve.

[0008] By adopting the above technical solution, the first servo motor is started, which drives the first threaded rod to rotate. The threaded sleeve can push the lifting plate up and down, raising the frame in the frame slot to a height that is convenient for the clamping components to hold.

[0009] To achieve limit control of the lifting platform: The lifting platform is further configured such that a frame groove is provided inside the lifting platform, and two telescopic rods are fixedly installed at the lower end of the lifting platform, with the other side of the telescopic rods fixedly connected to the bottom of the operating table.

[0010] By adopting the above technical solution, two telescopic rods are set to limit the movement trajectory of the lifting plate, preventing the first servo motor from driving the lifting plate to rotate synchronously through the first threaded rod, and instead causing it to reciprocate.

[0011] To achieve the fixation of the fixed connecting plate: The configuration is further defined as follows: four connecting rods are bolted to the inside of the fixed connecting plate, and the other side of the connecting rods is fixedly installed on the operating table.

[0012] By adopting the above technical solution, the connecting rods around the perimeter connect the fixed connecting plate to the operating table, keeping the fixed connecting plate in a fixed position and preventing the fixed connecting plate from becoming unstable when the second threaded rotating rod rotates, which would cause the clamping to deviate.

[0013] To guide the clamping direction of the clamping components: The configuration is further defined as follows: a first fixing rod is fixedly installed on both sides of the fixed connecting plate, a rotating block is rotatably installed on the outer surface of the first fixing rod, and a collar is fixedly installed on both sides of each rotating block, with one collar sleeved on the outer surface of the first fixing rod and the other collar sleeved on the outer surface of the second fixing rod.

[0014] By adopting the above technical solution, one side of the rotating block is fitted onto the outer surface of the first fixed rod, and the other two sides are fitted onto the second fixed rod. When the arc-shaped movable part is pushed forward, the second fixed rod moves forward synchronously, causing one side of the rotating block to move forward, while the other side of the rotating block is fixed in position, which will drive the protective rubber pads on both sides to the clamping angle.

[0015] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Component 3 includes a sliding cylinder block 31, which is slidably mounted on the outer surface of the second threaded rotating rod 22. A connecting block 32 is fixedly mounted on the outer surface of the sliding cylinder block 31. Arc-shaped movable parts 33 are rotatably mounted on both sides of the connecting block 32. The connecting block 32 and the arc-shaped movable parts 33 are connected by a connecting limit rod 34. Limiting rings are provided on both sides of the connecting limit rod 34. A second fixing rod 35 is fixedly mounted inside each arc-shaped movable part 33. A clamping block 36 is fixedly mounted on the front end of each arc-shaped movable part 33. A protective rubber pad 37 is bolted to one side of the clamping block 36.

[0020] In this embodiment, as Figure 1 and Figure 2 As shown, the operating table 11 is equipped with a first servo motor 13. The first servo motor 13 is fixed to the base plate of the operating table 11 by bolts. A first threaded rod 15 is rotatably installed on the upper end of the first servo motor 13. A threaded sleeve 16 is slidably installed on the upper end of the first threaded rod 15. A lifting plate 17 is fixedly installed on the upper end of the threaded sleeve 16.

[0021] In this embodiment, as Figure 1 and Figure 2As shown, the lifting platform 17 has a frame groove 18 inside, and two telescopic rods 14 are fixedly installed at the lower end of the lifting platform 17. The other side of the telescopic rods 14 is fixedly connected to the bottom of the operating table 11.

[0022] In this embodiment, as Figure 1 and Figure 3 As shown, four connecting rods 24 are bolted to the inside of the fixed connecting plate 23, and the other side of the connecting rods 24 is fixedly installed on the operating table 11.

[0023] In this embodiment, as Figure 1 and Figure 3 As shown, a first fixing rod 25 is fixedly installed on both sides of the fixed connecting plate 23.

[0024] This clamping fixture for bicycle frame processing operates as follows: First, during installation, the surface of the lifting plate 17 must be flush with the bottom surface. Then, the user places the bicycle frame in the frame slot 18 and starts the first servo motor 13 (model: MELSERVO-J4), which rotates the first threaded rod 15. This, in conjunction with the telescopic rods 14 on both sides, provides a limiting position, causing the threaded sleeve 16 and the lifting plate 17 to move, raising the bicycle frame to a suitable height. At this point, the second servo motor 21 (model: Kinetix VPC) is started, rotating the second threaded rod 22. This simultaneously causes the connecting block 32 and the arc-shaped movable part 33 to slide forward, pushing the arc-shaped movable parts 33 on both sides... 3. Moving forward, the clamping block 36 guides the arc-shaped movable part 33, causing the arc-shaped movable parts 33 on both sides to clamp inward, ultimately clamping the frame. The protective rubber pads 37 on both sides can prevent damage to the vehicle while clamping the frame. Then, the first servo motor 13 reverses, and the lifting plate 17 moves down. The user stands on the surface of the operating table 11 to process the frame. After processing is completed, the above operation is repeated. The first servo motor 13 drives the lifting plate 17 to rise, the second servo motor 21 reverses, the clamping blocks 36 on both sides are released, the frame is placed on the lifting plate 17, the lifting plate 17 falls, and the user can take the frame away.
